在Panel上画直线（求方法）

[jimmy893]

哪位大虾能给给写个方法，接5个参数，分别是 panel1,x1,y1,x2,y2 这五个参数。
实现功能，根据坐标参数，在panel1上画一条直线

  public void ImageLine(Panel p_Panel, int p_X1, int p_Y1, int p_X2, int p_Y2)
        {
            Graphics _Graphics = Graphics.FromHwnd(p_Panel.Handle);
            Pen _Pan = new Pen(Brushes.Red, 2);
            _Graphics.DrawLine(_Pan, p_X1, p_Y1, p_X2, p_Y2);
            _Graphics.Dispose();
        }

panel1_Paint
Graphics g = panel1.CreateGraphics();
Pen red = new Pen(Color.Red, 3);
g.DrawLine(red, 1, 1, 10, 10);

priviate void drawLine(Panel panel1,int x1,int y1,int x2,int y2)
{
Random r1=new Random ();
Random r1=new Random ();
x1=r1.Next(panel.width);
x2=r2.Next(panel.width);
y1=r1.Next(panel.Height);
y2=r2.Next(panel.Height);

Graphics g = panel1.CreateGraphics();
Pen p1 = new Pen(Color.Red, 3);
g.DrawLine(p1, x1, y1, x2, y2);
g.Dispose();

}
